JitsiId (jid) function

Anyone has any idea what function is being used to generate Jitsi-Id for participants ( eg 90ecb5ad ) is it some part of UUID?

I’m just guessing, but I suspect the JIDs are generated by prosody.

And from what I can tell, prosody generally uses the functions in util.id to generate random IDs.
